I got a deluxe sample of this product as part of a 500 pt perk and it lasted me about two years of using it to set my under eye concealer.

This is a really great product. I don't have a lot of experience with setting powders but this one did a great job preventing my concealer from caking and settling into the fine lines underneath my eye. It also never looked powdery on my tan skin, but deftly took care of any shiny-ness if I was oily or happened to over apply the highlighter.

The only problem with it is that it's messy. If I repurchased, I would probably get the compact rather than the loose powder and see if that works better for me. Right now, however, I'm using a beige urban decay eyeshadow to set my under eye and that's working just fine.
